Someone who enjoys pain. You could think of it as someone who cuts, or someone who likes being bitten.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

Someone who loves pain with all their mind, body and soul. They just might hurt themselves to feel excited.
